Roll engine with rolled dart (#14538)

* Roll engine to pre-dart roll

* Roll engine to pick up updated dart

* Apply Map changes

* Move to dev.22

* Fix some analysis issues

* Silent analyzer

* More consts

* More const massaging

* Yet more const massaging

* Yet more const massaging

* Use nonconst()
